Double Shot of CO please

Not only was the adjacent unit blowing Flue Gas into it's Fresh Air Hood the heat exchanger had holes in it.
Stupid me, I didn't notice the redone gas piping.
You can see the back unit had a riser, there was a pile of them in the corner.

You can put it up on a photo hosting site and then use the [ img] and [ /img] tags around the direct link to the picture, just no spaces inside the square brackets, I put them in there so the forum software doesn't process "and" as a link to a pic. It would look like this (just without the spaces): [ img]http://www.any-photo-hosting-site.com/picture.jpg[ /img]

Both the IFGC and NFPA 54 require sediment traps on all gas utilization equipment except lumaires, washers, ranges and dryers.

Drips on the other hand are used only where there is wet gas. These shall be provided at the outlet of the meter and anywhere condensate could collect.

IRC G2419.9 (IFGC 408.3) ..."a drip shall not be located where the condensate is subject tofreezing.

A drip is located inside the building a foot from the meter entry. Sediment traps are located at each appliance. They are NOT the same, as I have been repeatedly explaining here and in every technical discussion on traps I find. Those traps that are missing from exterior appliances are a code violation for Not being there. You AHJs need to re-read the code books and learn the difference between a 'drip' and a 'trap'. It would also help if everyone eradicated those terms "drip leg" and "dirt leg" from their lexicon and substituted "sediment trap" , which is their legal name.

If you leave off a sediment trap or fail to notify a client of one missing and there is an incident with damages or injuries then you will be liable even if your ignorant AHJ told you not to install them. He does not have the legal capacity to diminish the code and those traps are required by all mfrs and both gas codes. Install them. Done

heartman,
Thanks for the heads up. So i grabbed a Carrier IOM off my desk and it shows a sediment trap with drip leg wordage as well.

Finally someone takes the time to explain. Were i live I have never seen a trap before any appliance like i see people nagging about on this site. I just tought it was a northern thing fo the cold. THX. Plummers here are responsible for the gas line all we have to do is stub out with a piece of flex.
